Background:
The iliopatellar band (IPB) is an anterior extension of the iliotibial tract (ITT) that has been described as contributing to lateral knee stability. This study aimed to investigate the anatomical features of the IPB, focusing on its branching pattern from the ITT, the extent of patellar coverage, and its attachment.
Methods:
We examined 64 specimens among 39 embalmed adult South Korean cadavers through dissection, microcomputed tomography, and sectioned images.
Results:
The IPB consistently covered the patella and the patellar tendon but to different extents. Micro-CT revealed the division of the IPB into external and internal layers, each possibly having specific functions in force distribution and knee stability. The lateral patellofemoral ligament joined the internal layer or continuously attached to the lateral border of the patella, which possibly may assist in maintaining patellar alignment.
Conclusions:
These anatomical insights into the layered configuration and attachments of the IPB may support a better understanding of knee biomechanics and surgical approaches, particularly in the context of ITT tightness and lateral patellar tracking.

Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...
